Idaho Business Entity Search: How to Look Up Any LLC or Corporation on the Secretary of State Site

You need to confirm that a company is registered in Idaho, find out who its registered agent is, or check whether its annual report is on track. The Idaho Secretary of State's business search, run through SOSBiz, answers those questions for every LLC, corporation, and other registered entity in the state. This guide walks through the Idaho business entity search step by step, explains each field on an entity record, and marks what the search cannot tell you.

Informational content only. This article is not legal or tax advice. If you are relying on a lookup for a contract, a lawsuit, a lender requirement, or a tax filing, talk with a qualified attorney or CPA before you act.

Where to run the Idaho business search

Idaho entity records are searched in one place: the SOSBiz business search. The Idaho Secretary of State runs the portal, and the search covers the whole state. You do not need to check county offices to find out whether an LLC or corporation is registered. Counties do not issue a general business license, which matters later in this guide, but they do not keep the entity registry.

Use the same portal to look up a DBA. Idaho files assumed business names with the Secretary of State, not the county, so the statewide search is the right starting point for a trade name too.

Step 1: Search by name and check near matches

Start with the exact legal name from the contract, invoice, or formation paperwork. Then search the variations that Idaho's naming rules make likely:

• Entity endings. When Idaho tests whether a name is distinguishable, it ignores entity-type words such as LLC or Inc. (Idaho Code 30-21-301(c)). A search for Summit Electric can therefore return Summit Electric LLC and Summit Electric, Inc. side by side. Check every match.
• Abbreviations. Under Idaho Code 30-21-302(d), Limited may be abbreviated Ltd. and company may be abbreviated Co.
• Spelled-out and shortened forms. Try both, because a record may use the full word where your paperwork uses an abbreviation.

Step 2: Read the entity record

Open the record and read every field before you draw a conclusion. These are the fields that matter most.

Status

The status line shows how the Secretary of State currently records the entity. Read it literally. If the record does not show an active entity, take a closer look before you assume the company can sign contracts or operate under that name. If the record reads administratively dissolved, see the reinstatement section below.

Registered agent

The registered agent is the person or business that receives legal papers and official notices for the entity. Every Idaho entity must continuously maintain one. The agent needs a physical Idaho street address, since P.O. boxes are not accepted, and must be available during normal business hours. An owner may act as their own registered agent using an Idaho address. A DBA cannot serve as a registered agent, so if a trade name appears in that field, do not accept it as valid. Confirm with the Secretary of State.

Principal office

This is the main office address the entity reports. Compare it to the address on your paperwork. A mismatch is not proof of anything, but it is a reason to ask questions.

Governors

The record lists the governors, the people the entity has reported as running it. Treat this as what the state has on file. It is a starting point for finding the people behind the entity, not a complete ownership picture.

Annual report due month

Every Idaho entity must file an annual report each year, beginning one year after formation. For an LLC, the report is due each year before the end of the month in which the Certificate of Organization became effective. For a corporation, it is due before the end of the month in which the Articles of Incorporation became effective. The record shows the due month, which is the month the entity was formed or registered (Idaho Code 30-21-213(c)). Idaho Code 30-21-214 lists the annual report fee as no fee, but filing is still required. Compare the due month to today's date. If you cannot tell whether a report is current, confirm with the Secretary of State before you rely on the record.

Assumed business names

Any DBA the entity has filed is tied to its record. A DBA is a trade name the business uses, not a separate legal entity, so a DBA result leads you back to the entity that filed it.

Step 3: Find the owner or the agent

Start with the registered agent. The record names the agent and the Idaho address where legal papers must be delivered. If the agent is a commercial registered agent, that agent is the route for formal notices. If the agent is an individual or the owner acting for the company, the name and address on the record are your contact for service.

For ordinary business contact, such as a vendor question or a customer complaint, use the company's own phone number, email, or website. For a formal demand or a dispute, send it through the registered agent and talk with an attorney about the next step. If ownership matters to a deal, do not treat the governors list as complete. Ask for the operating agreement or bylaws, or have an attorney request them.

Searching for a corporation

Corporations use the same SOSBiz search and the same record layout. A corporation forms by filing Articles of Incorporation (General Business) with a $100 filing fee. The annual report rules match the LLC rules: the report is required each year, beginning one year after formation, and it is due before the end of the month in which the Articles became effective.

Because LLCs and corporations are tested against the same name rules, a corporation and an LLC can appear to conflict with each other. Read both records before you decide a name is available.

Searching for a DBA (assumed business name)

Idaho's DBA is the Certificate of Assumed Business Name, filed with the Secretary of State. An online filing costs $25. A paper filing costs $45, which includes a $20 manual data entry surcharge. The filing stays active until it is canceled and is not subject to renewal. Current forms are on the Secretary of State's business forms page.

Checking whether a name is available

An entity search shows what is already on file. It does not reserve anything. To hold a name you plan to use, the Secretary of State offers a name reservation under Idaho Code 30-21-303(a). A reservation holds the name for 120 days. The Secretary of State's paper form describes this period as four months, so plan around 120 days and confirm the exact terms on the forms page. A reservation costs $20 online or $40 on paper.

Availability turns on distinguishability. The Secretary of State compares the proposed name with existing, reserved, and registered names, and it ignores entity endings such as LLC or Inc. (Idaho Code 30-21-301(c)). The name must also meet Idaho's wording rules. An LLC name must contain limited liability company, limited company, L.L.C., LLC, L.C., or LC, and no name may falsely state or imply government affiliation.

Reinstatement when a record says dissolved

An entity that has been administratively dissolved can apply for reinstatement within 10 years (Idaho Code 30-21-603(a)). Check the Secretary of State for the current reinstatement fee and filing steps. Confirm the entity's status before you sign new agreements with it.

What the search does not tell you

A registered entity is not a licensed business. Business.Idaho.gov states it plainly: 'Idaho does not have a state business license. Registering your business is a registration, not a license.' Keep these levels separate:

• State. There is no statewide general business license. Idaho also has no statewide general contractor license. Contractors register with the Idaho Contractors Board at the Division of Occupational and Professional Licenses (DOPL), and you should confirm the current requirements with DOPL.
• County. Counties do not issue a general business license.
• City. Some cities require a general business license or permit. Others license only specific activities. Check with the City Clerk in the city where the business operates, and use the Business Wizard at business.idaho.gov to see which agencies and permits an activity needs.
• Short-term rentals. Since July 1, 2026, no city or county may require a license, fee, permit, or registration for a short-term rental under HB 583. State and local lodging taxes still apply.

Taxes are a separate question. Idaho's income tax is a flat 5.3%, and the state sales tax is 6%. Idaho has no local sales tax outside voter-approved resort cities. The Idaho State Tax Commission sets out the filing rules, and a CPA can tell you which return your entity must file.

Common lookup mistakes

• Searching only the exact name and missing a near match with a different ending.
• Treating a DBA as a separate company instead of a trade name tied to an entity.
• Reading the governors list as the complete ownership picture.
• Assuming the registered agent's address is where the business operates.
• Assuming a search result confirms a license, a permit, or good standing for tax purposes.

Frequently asked questions

Do I need to search the county too?

Not for entity registration. The Secretary of State handles LLC, corporation, and DBA filings statewide. Counties do not issue a general business license, but some local permit questions are answered at the city level, so check there.

Does a registered LLC need a business license?

Registration with the Secretary of State does not create a license. Whether you need a city license, a permit, or a profession-specific license depends on the city and the activity. Confirm with the City Clerk and the Business Wizard.

What if the record has wrong information?

Do not try to change it yourself. If the entity is yours, use the filing options on the SOSBiz forms page, or contact the Secretary of State to ask how to correct the record. If the entity is not yours, a formal correction request should come from its owner or an attorney.

Next steps

Run the search, read every field, and write down the registered agent, the annual report due month, and any DBAs before you rely on an entity. If you are setting up your own company, the Idaho Small Business Development Center can help you think through formation questions. For a complex deal, a lawsuit, or a tax question, talk with a qualified attorney or CPA.
